Ineternet speed after the openvpn connection

[aneesh]

Hi,

My adsl speed is 4mbps but when I connect the openvpn and do a test (speedtest.net), I get only 1 mbps maximum. There are no other clients connect to the vpn. I am the only client. Then how it happens? How can I rectify this? Please help.
Thank you.

Hello,

Your upstream is between 1 and 1.5 megs, right?

Hi Stephen,

The down speed is 1mbps and up is about 600-700kbps.
Sorry for the late reply.
Thank you.

Thank you.

where is the openvpn server? is it in your house or elsewhere?

Your speed tests make sense, then. As your upstream becomes saturated with outbound connection requests, your downstream speeds with stabilize at a speed lower than what you might expect. This can also be affected by the vpn link itself using udp packets which are difficult to optimize (QOS-wise). If you have the inclination and are utilizing an OS that supports such things, you can look into a QOS method called ACK prioritization for the virtual device itself. Personally, the only operating systems I've implemented this on have been BSD/PF-based--I'm sure there are docs somewhere to do the same in Linux.
